Description
MSI PRO B840-P WIFI is an ATX motherboard with an AM5 socket, aimed at stable mid-range to serious work and gaming configurations. It is based on the AMD B840 chipset and supports the latest AMD Ryzen 9000, 8000, and 7000 series processors, giving you a direct path to the current generations of CPUs. You get modern DDR5 memory with high overclocking potential up to 8000 MHz (O.C.) and a rich selection of expansion slots and storage. The built-in Wi-Fi 7 and 2.5GbE LAN provide you with flexibility for a fast network whether you are wired or wireless.
What you get
With four DDR5 slots and a maximum of 256 GB RAM, you can build a machine that can easily handle heavy multitasking, gaming, streaming, and working with demanding applications. The two M.2 PCIe 4.0 x4 slots – both directly connected to the CPU – provide fast NVMe drives for the operating system, games, and software without worrying about where the bottleneck will occur. The four SATA 6.0 Gb/s ports with RAID 0/1/10 allow you to add large HDD/SSD arrays – both for gaming and for backup or working with large files. The built-in Wi‑Fi 7 and Bluetooth 5.4 eliminate the need for additional cards for wireless connectivity, which is convenient in cleaner, minimalist builds. Realtek ALC897 7.1 audio gives you direct sound for gaming, movies, and voice chat without having to immediately think about a separate sound card.
- Socket AM5 and support for Ryzen 9000, 8000, and 7000 series, giving you a wide choice of modern AMD processors for gaming and productivity.
- Four slots for DDR5 memory with a capacity of up to 256 GB and frequencies up to 8000 MHz (O.C.), suitable for fast configurations and serious multitasking.
- Two M.2 PCIe 4.0 x4 slots (from CPU), with the second supporting devices up to 22110, ideal for high-speed NVMe SSDs for the system and projects.
- 4 x SATA3 6.0 Gb/s with support for RAID 0/1/10, allowing you to combine performance, capacity, and redundancy for more secure storage configurations.
- Diverse PCI-E slots – one PCIe 4.0 x16 from CPU for a graphics card plus additional PCIe 3.0 slots for expansion cards (audio, capture, network, etc.).
- Built-in connectivity with Wi‑Fi 7, Bluetooth 5.4, and Realtek 2.5GbE LAN, so you are covered for both high-speed wired internet and the latest wireless standards.
- A rich selection of USB: a total of multiple USB 2.0, USB 5Gbps, and USB 10Gbps ports, including Type‑C at the front and back, for modern peripherals and fast transfer.
- Standard ATX form factor and power connectors 24-pin + 8-pin, facilitating integration into mainstream mid-tower cases and PSU configurations.
Who it is suitable for
This motherboard is suitable for gamers and power users who want an AM5 build with DDR5, fast NVMe drives, and stable network connectivity without unnecessary flashy "gaming" design. It fits well for both a 1080p/1440p gaming machine and a workstation for programming, file processing, and office/remote work. If you are looking for extreme overclocking and PCIe 5.0 for GPU/SSD, you may miss the latest high-end features here.
The combination of AM5, DDR5 up to 8000 MHz (O.C.), two M.2 PCIe 4.0 slots, and Wi‑Fi 7 makes the MSI PRO B840-P WIFI a very reasonable base for a modern and long-term build without unnecessary compromises. You get a balanced platform that you can easily upgrade over time according to your needs.
